Every filmmaker these days is very keen on promotions, because they are the ones that bring huge collections on first day by bringing huge audiences. In Bollywood, they understood this dynamics well.
For next Friday's (March 18th) release "Kapoor And Sons", the film's star cast including Alia Bhatt, Siddharth Malhotra and Fawad Khan are busy touring various North Indian cities to promote it. As part of this tour, everyday they are wearing new style of t-shirts that have text printed on them.
Seen in this picture is one such t-shirt where the title of the film is printed by each word on three of them, and they together make the name. Same is the case with date. That's wow promotion.
